The number of Chinese companies which made it on the Fortune Global 500 reached 129, surpassing the US for the first time as the latter country had 121 companies on the list, the magazine reported on Monday.
China's largest State-owned oil and gas company Sinopec Group climbed one spot on Fortune's Global 500 list, reaching second place due to sharp gains in both revenue and profits last year.
Behind Walmart - whose revenue was U$514.41 billion(S$701.8 billion) - Sinopec Group saw a 26.8 per cent growth in revenue to U$414.65 billion last year, and profits in 2018 reached $U5.85 billion, a year-on-year growth of 280.1 per cent.
The strong results were driven largely by robust domestic demand for gas and chemical products, the report said.
Another Chinese company, China National Petroleum, grabbed the fourth spot with revenue of U$392.98 billion in 2018, followed by State Grid with $387.06 billion.
With revenue of U$69.85 billion, JD.com continues to lead Chinese internet companies, reaching the 139th spot on the list.
Alibaba Group Holding, whose revenue reached U$56.15 billion, was the company with the fastest growth rate, jumping 118 spots to 182.
Gree Electric Appliances Inc and Xiaomi Corp were newcomers to this year's list, and 9-year old Xiaomi was the youngest company among the Global 500.
Three Chinese companies were included in the top 10 of the Fortune Global 500, and are mainly involved in natural resources.
